TO ALL WHOM IT MAY CON CERN:

Be it known that I, JOHN G. BUZZELL, of Lynn, in the county of Essex, and State of Massachusetts, lfave invented a new and improved Carriage-Wheel; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

Figure 1 represents a. face view, partly in section, Vof my improved carriage-wheel.

Figure 2 is a vertical central section ofthe same.

Similar letters of reference indicate corresponding parts.

This inventionrelates to that class of carriage-wheels in which metallic spokes are used, and consists in the construction and arrangement of parts, as will be hereinafter nrore fully described. v

A, in the drawing, represents the hollow hub of a wheel. The sameis made of metal or other suitable material, of cylindrical or truncated conical form, and has two annular chambers a a, formed around its outside, near its ends, the face-plate b of each chamber a being the flangefa-c-ap,l, one such cap being screwed upon each end of the hub, as shown in fig. 2. i

C C are the spokes, made of Wire or other suitable material, Their inner ends are fitted through the rims of. the chambers a, Vand are fastened therein by means of nuts o c, as shown, while their outer ends are fitted through the felloe D, aud fastened to elliptic springs E E, that are inserted in recesses formed in the outer edge nf the felice, as shown, each spoke being fastened to its separate spring, as shown, or each spring, if, desired, holding two or more spokes.

The springs E are supported at their ends, while the middle portions, in which the ends of the spokes are fastened, are `ree to yield to outside pressure, thereby making the whole felice elastic and not liable to excessive strain. The ends of the spokes are screwed, riveted, or otherwise fastened to the springs. When the felloe should be compressed at one part, the aiected spoke will be pushed in, and its nut e will then be pushed into the chamber a, to be replaced by the reaction of the spring E. i

The spokes are curved, as shown in lig. 2, their outer ends being at right angles to the felloe, to be out of the way, while their inner ends are inclined to lead towards the chambers o, and to properly brace the rim.

A tire of suitable construction may be fitted around the felloe in suitable manner.

By unscrewing the .caps B, the inner ends of the spokes, with their nuts, will be exposed to view, to be adjusted at will.

The chamber a may be lined with leather or other material, as shown', to prevent the rattling of the nuts in such chambers, as specied.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In the carriage-wheel, consisting of the hub A, having the chambers. a a and the caps B B of the spokes C C, bent in the manner specified, the springs E inserted in the felloe D, all arranged and operating substantially as herein shown and described. I
